Just playing around with the queueing options on my own ethernet firewall box at home here (rb153).
I had problems where when uploading (with ssh scp), other interactive traffic crawled and barely worked. I changed the ethernet queue type, made some minor adjustments to it, then setup a mangle to mark ssh traffic, then made a simple queue for the mangle, so the pcq would be applied to it.
Now, multiple ssh activities behave much nicer together. ssh logins work smoothly while ssh scp is uploading. It's a good setup now.
Anybody notice anything I am off about or should have done differently?
